Research Peptide Documentation Checklist
Research peptide documentation should connect the named compound, labeled quantity, lot, testing method, laboratory, dates, and reported results to the material under review. Use this field-by-field checklist to evaluate COAs, identity evidence, purity results, lot traceability, and documentation gaps before laboratory procurement.
Material identification
- Compound name and verified synonym, where applicable
- Declared form or salt, when relevant
- Lot or batch number
- Quantity and labeled specifications
Analytical documentation
- Report identifies the tested sample and matching lot
- Testing method is named
- Results include units and acceptance criteria where applicable
- Laboratory and report date are visible
- Report distinguishes purity from molecular identity
- Limitations are not presented as broader guarantees
Traceability
- Supplier records connect the received material to the tested lot
- Label information matches the report
- Revised or superseded documents are clearly identified
- Documentation remains accessible for later protocol review
Supplier transparency
- Business identity and contact information are available
- Research-use restrictions are clear and consistent
- Testing explanations avoid overstating what one method proves
- Policies explain purchasing eligibility, shipping, refunds, and prohibited uses
Questions to resolve before procurement
If a report lacks a lot number, method, laboratory, date, or clear result, request clarification. Do not assume a generic example report applies to the material being considered.

RECORD REVIEW
Read the complete record, not one headline number
A documentation review works best as a chain of evidence. Start by matching the material name and labeled quantity, then connect the physical lot to the laboratory report. After that, identify exactly what each method measured and what the reported result does not establish.
Identity
Does the report support the stated molecular identity, and is the method appropriate for that question?
Relative purity
Does the report define the chromatographic method, integration approach, and result being reported?
Quantity
Is the result an absolute mass or assay measurement, rather than an assumption based on HPLC area percentage?
Traceability
Do the lot, quantity, supplier, laboratory, report number, and verification destination agree?
Continue with the field-by-field COA guide, the annotated HPLC guide, or the searchable COA Library.
PLAIN-LANGUAGE ANSWERS
Research peptide documentation questions
What documentation should accompany a research peptide?
A useful record should identify the compound, labeled quantity, lot or batch, supplier, testing laboratory, report number, analytical methods, reported results, and any limits stated by the laboratory.
Is an HPLC purity percentage the same as peptide identity?
No. HPLC area percentage describes relative detector response for included peaks under the stated method. Identity is a separate analytical question and may require mass spectrometry, reference standards, or other complementary evidence.
How do I match a Certificate of Analysis to a vial?
Compare the compound name, labeled quantity, lot or batch, supplier, report number, laboratory, and any verification record. A QR code is only a route to a record; the identifying fields still need to agree.
What should happen when the label and laboratory report do not match?
Treat the documentation as unresolved. Do not infer that a report belongs to the material when the compound, quantity, lot, supplier, or report identifiers disagree.
